Final state interaction and \Delta I=1/2 rule
E.P. Shabalin
TL;DR
This paper challenges the common belief that final state interactions (FSI) enhance the =1/2 amplitude in kaon decays, arguing instead that FSI does not increase its magnitude.
Contribution
The paper provides a theoretical argument showing that FSI does not enhance the =1/2 amplitude, countering previous widespread opinions.
Findings
FSI does not increase the absolute value of the =1/2 amplitude
Challenges the common belief about FSI's role in kaon decay amplitudes
Provides a theoretical perspective on the =1/2 rule
Abstract
Contrary to wide-spread opinion that the final state interaction (FSI) enhances the amplitude <2\pi;I=0|K^0>, we argue that FSI does not increase the absolute value of this amplitude.
